I used a few containers of it 10 years ago....
It left too much white residue on my quick connects (even at less than recommended ratio) which led to a lot of issues with the diesel burner flow switch being stuck on "on" position. If you know what that means you'll understand how dangerous that is!
Flame on full blast....while no water is traveling through the system. Sometimes you can hear the diesel burner rumble with the wand laying on the carpet unused.... So you run out to the truck and the pressure gauge is already climbing over 2000psi....!!
It's really a bad design....but I digress.
Rage -in my opinion- is pointless, when you're using a decent prespray and prescrub.
